I have had a treo 700wx from verizon for about 2 weeks and have tried 2 differant bluetooth devises. One beining the Jabra Bt135Z. The other being the Motorola HS850. The problem I am having is I cannot call from my contacts with either. If I hold the button on the bluetooth it will dial the last number that was called from the phone. I started out with the Jabra the talked to palm and was informed it was not a recomended head set because it had not been through their test. The Motorola has been but still won't work.
